Application filed April 6, 1916. Serial No. 89,363.

To, all 'whom it may concern Be it known that I, ELor NORDSTROM, a citizen of the United States, residin at Newark, in the county of Essexl and tate of New Jersey, and useful Improvements in Bottle-Capping Machines, of which the following is a specification.

This invention relates to bottle capping machines and has for its primary object to provide an improved construction, combination, and arrangement of parts in a machine oflthis character, whereby a cap is applied to a bottle and partly crimped by one mechanism and completely crimped in another mechanism to which it is conveyed after it passes from the cap-applying mechanism One of the objects of the present invention is to provide improved means for partially criming a cap upon a bottle to prevent its accidental displacement while the bottle is being conveyed into position to have the cap securel crim ed in position.Y Other and further'ob3eets willappear in the specifica'd tion and be pointed out in the appended claims, reference bein had to the accompanying drawings whlch exemplify my in vention in its preferred embodiment and in which drawings Figure 1 is a front elevation of a machine constructed in accordance with the principles of my invention, parts being broken away;

Fig, 2 is scale of the combined cap-applying and preliminary lcrimping mechanism, adjacent parts 'of the machine being shown in section;

Fig. 3 is a similar viewA showing the parts a front elevation on an enlarged in changed positions;

Fig. 4 is a side elevation of the same showing conti nous parts of the machine, parts being bro en; away and parts shown in section.

Fig. 5 is a top plan view on an enlarged scale of the conveyer mechanism, parts being broken away;`

Fig. 6 is a side elevation of the same, parts being broken away and parts shown in section; 4

Fig. 7 is an axial section on an enlarged scale of one of the cap-crimping units, parts being shwn in elevation.

In the embodiment of my invention shown on the drawings, a frame 1 is provided with suitable means for mounting a plurality of nuts 2, which may be have invented certain newA `The other end of sai operated in any suitable manner to raise and lower the threaded bolts 3, which carry a suitable bedplate or table 4, over which filled bottles may be fed by suitable mechanism therefor. For this purpose, a double star ranged adjacent one end of the plate or table 4 to laterally `displace the bottles one by one into a line of feed over the plate or table 4 in such a way as to pass successively under the' capping and preliminary crimping mechamsm as well as the final crimping mechanism, such mechanisms being hereinafter fully described. As ointed out in my copending application, ii ed August 31st, 19.15, Serial Number 48,210, means for feeding the vessels are provided byreci rocatory pairs Vof bottle engaging gripper ars 6 and 7, the former being adapted to move the filled bottles one b one from the star wheels 5 into position be ow .the cappin and preliminary crimping mechanism an thence to a point Within the reach of the reciproea tory members 7, which moves said bottles two by two into position beneath the double crimping heads to be hereinafter referred to.

As shown in Figs. 5 and 6, shaft 118 has keyed thereto a sprocket wheel 119, over which runs a chain 120 for rotating a smaller sprocket 121 keyed`to a shaft 122 (see Fig. 6). The shaft 122 carries a gear 123 which meshes with a gear 124 mounted on a spind1e125 which carries a bevel gear Cope'rating with 'the rotary conveyer is a curved guide 128,with a tangential-portion extending along the table 4. As shown in Fig. 45,1 said rotary conveyer places the vessels successively into position to be en# gaged by a reciprocator'y conveyer. Keyed to the shaft 125 is a crank arm 129'to which one end of a connecting rod 130 is pivot-ed.

connecting rod is pivoted `at,131 to one of a pair of arms 132 which are geared to` ether and journaled on slides 45. Arrange above and oscillatable with the arms '132 respectively, the upper arms 134 are geared to similar arms 135 which are also journaled on the slides 133. Arms 134 and 135 carry brackets 13G and 137, upon the outer ends of which the opposite ends of a gripper bar 6 are pivotally mounted; Said gripper bar carries suitable grippers 139.` A crank arm 1-11 car- Patented May 13,1919.

wheel 5 is ar-` ried by the shaft 122 is connected to 'one `end of a connecting rod 142, the other end of said connecting rod being pivotedon a pin 143 carried by one of a pair of interengalging lever arms mounted on 1 pintles whic are fjournaled in oppositely arranged slides 45. Said slides reciprocate in the dove-tailed grooves formed'in the aprons to 'feed table 4, the above mentioned slides 45 being mounted in the [same grooves. The connecting rod 1 42 is thus adapted to simultaneously oscillate ivotally mounted arms 46 which are geared) at 47 for this purpose. Pivotally connected'to the arms 46 on elther side of the feed ta'ble is a gripper bar 7 which is also provided with grippers 139.

A shaft 8 which carries a ily-wheel 9, is

journaled in bearings 10,11 and 12 and receives its power in a manner shown and described in my copending application referred to above. Power from the shaft 8 is delivered to the'preliminary crimping and clamping mechanism shown in Flgs. 2, 3 and 4 by suitable gear and shafting connections shown fully in the above mentioned application, such power being thus 'trans-v mitted Ito a connecting rod 13 (see Fig. -4)

ivotally connectedV at 14 to the bell crank ever 15, which Iis journaled on a pin 16. The forwardly presented arm of the bell crank lever 15- is bifurca-ted, the branches 16 thereof being pivotally connected to a yoke 17 which is apertured to accommodate the upper end of aplunger 18, the upper end of said plun er being rovided with a collar' the yoke 17 arethe preliminary crimping* elements ,29 which are bowed outwardly intermediately of their ends, but have their lower ends offset inwardly and provided` with crimping jaws 30. A- rotary table 31 is provided with a plurality of\capshaping dies or sockets 32 which are flanked on either side by openings 33 to accommodate the downward movementof the crimping jaws 30. The lower end of the plunger 18- is pro- `vided with an. enlargement' 31 which is adapted to flatly engage the top wall of a cap 35 Awhich is carried in the socket 32. When the yoke 17 is moved downwardly, the plunger 18 will displace the ca from the socket 32 on to the neck 36 of all ottlewhich has been automatically disposed in position to receive the same. The. crimping elements carried 29 partake of the downward movement of the plunger V18 and passin through the openlngs 33 on either side of t e cap-holdin g socket, engage thelobes 37 of the ca 35.

'If the downward movement of the yo e 17 continues, the movement of the plunger 18 is interrupted while the crimping elements 29 continue their downward movement, thus serving to displace the lobes 37 about the neck 36 of the bottle. Toward vthe end of this movement, the outwardly bowed portion of the crimping elements 29 are pressed inwardly between rollers 27, 28, in such a way as to force the crimping jaws 30 in under the neck 36 sufficiently to secure the cap 35 against displacement during the subsequent movement of the bottle to the complete crimping mechanism. The rotary table 31 is carried by the lower end of a shaft journaled in the bearing 38, the said shaft being driven b suitable connections from the shaft 8. ferrinv now to Fig. 1, the shaft 8 carries a beveled pinion 39 which meshes with a bevel gear 40 on the upper'end of a shaft which vertically reciprocates the compound crimping head 41, said crimping head being provided with radially disposed crimping elements 42.

The'band 41 which is reciprocably mounted serves to support a socket 221 within which. is reciprocably mounted a slide 222, held against rotation by means of ,av spline 223. The vslide 222 is carried by `a rod 224,

which passes through the upper end of socket 221 and is limited in its downward movement'b an adjustable cap or nut 225. Interposed tween the upper end of the socket and the slide `222 is a. spring 226. The lower end of the rod 224 carries a capengaging member 227. Radiallydisposed with respect to said member 227 are a plurality of crimping elements 42 which oscillate about theirrounded lugs 229. The elements-42 project through radial slots in slide 222 and are normallyheld in outward position b means of springs 230, which are liy studs 231 on projectin of slide 223. Whenever the soclet 221 is forced downwardly, the member 227 rests upon the cap and 'forces it into the position on the neck of a. bottle. When the slide -222 -is broughtvto rest, a plurality of plungers 232 which are mounted in flanges 233, are forced down onto the elements 228 so as to move them into `the position to crimp'the portions will now be readihl .understood and bl'iefly described is as follbws:

Filled vessels are fed one by one along the -plate or table 4 under the capping plunger 18, .which descends and forces a capfrom one ofthe sockets in the rotary plate 31', down on to the noch of the botth` therebeneath.
